To all 'whom t may concern:

Be it known that ive, LAWRENCE lll. JOHN- SON, 'fl'rro '.l. l) etsen. and Leontine A. Pori. citizens ot the linited States of Amer* ica, and residents of Melrose, in the county of Middlesex, Malden, `in the county of Middlesex, and tiaugus, in the county of Essex, respectively, all of the State of Massan chusetts, have invented certain newv and useful improvements in .Rough l'ounders, of which ythe following is a specification.

This invention relates to sole rough round- `ers and channeling machines to be useed in the manufacture of boots and shoes and is an improvement on the machine shoivn and described in the Patent No. 1,149,369, issued August 10. 1915,' to Lawrence lil. Johnson.

One object of the present invention is to provide a machine which can be used equally as Well. on new Shoes in the process of inanufacture, or upon old shoes being repaired.

Another object of the invention is the provision of means whereby the cutting chisel holds the Work in position While the channeling knife is Operating.

.-\V further object is the provision of novel means for feeding the Work.

further object is the provision of means nf'bereby the channeling tool may follow the inclination of the sole While the latter is bein.;` operated upon.

Another object is the provision of means whereby the channeling` toolmay be moved out of commission when it is desired to trim the sole without forming' a channel therein. A further*object` of the invention is the production of a novel means of adjusting the edge page.

il. further object is the provision of tivo edge gages, one for the welt and the other for the upper,` and `either of Which may be used according' to the class of Work being performed.

linother object of the invention is the provision of means whereby the channeling lrnife may be adjusted relatively to the page so that the channel may be cut into the Sole at varyimi` dir'stances from the sole edge'. .another object is the provision of means whereby the channel knife may operate when the rough rounding chisel is not in operation.

The invention consists ot certain novel 'i construction and arrangement Serial No. 527,344.

'limited to the precise arrangement and organization of the instiiuinentalities as herein sho-Wn and described, exceept as required Vby the scope of the appended claims.

Of the drawings: Figure 1 represents a front elevationof a machine embodying;` the principles of the present inventionj f Figure :2 represents a side elevation ofv the same,

`Figure 3 represents a plan of said inachine,

Figure l represents a detail in elevation of a portion of the machine to be herein after referred to.

Figure 5 represents a rear elevation of the work support,

Figure 6 represents a. horizontal section of same on line 6, ti on Figure 5, and

Figure .7 represents a rear elevation of a feedingineinber adapted to be substituted for the channeling knife when the machine is beine; used for cutting a channel in a sole alreadyY shaped, Said view being drawn to an enlarged scale.

Similar characters indicate like parte, throughout the several figures of the draw@ ings. ln the drawings, 10 is the base of a frame 11 having),- bearings 12, in which is revolubly `mounted a shaft 13 adapted to be driven by a pulley 1eloosely mounted thereon,

rl'he Shaft 13 has secured thereto the cam iai nected by means of a rod to a suitable treadle mechanism, which may be of any well. known Construction and consequently is not shown in the drawings.

Then the treadle mechanism is operated 'to depress the arm 24, the lever 22 will cause the pulley 14 to be moved into a frictional. engagement with the fly wheel 13, in this mannereflecting the rotation of the shaft is soon as the pressure is released from the treadle mechanism., the pulley 14 will move outwardly on the shaft 13 and disengage itself from the fly wheel. 18.

rlhe fulcrum pin 23 is mounted on the 7 outer end of a bracket 26 secured to a column 27, to the upper end of which the base 10 is secured.

The fra-me 11 has extending therefrom a pin 28 on which is mounted the lever 29, the lower end of which is provided with roll 30, bearing against the cam 15. This leyer 30 is provided with a downward extension 31 between which and the pin 32 on the base 10 is a spring` 33 which retains the roll 30 in contact with the periphery of the cam. 15 at all times.

The upper end of the lever 29 is providedA with a bearing 34 in which is mounted a shank 35, the upper end of which forked as shown at 36 in Figure 1 of the drawings. Between the forked end 36 and the upper end of the bearing 34 is a spring 37, which forces the forked end 36 upwardly. Pivoted to the lever 29 at 36 is a lever 39 having formed therein a slot 40, into which extends a pin 41 secured to and extending outwardly from the shank 35, By means of this lever 39, the shank and the forked upper end 36 thereof may be moved downwardly in the bearing 34 against the tension of the spring 37. This movement is performed when it is desired to insert new work to be operated upon, and as soon as the new work is properly positioned, the pressure upon the lever 39is released and the spring 37 moves the work upwardly against the member 42.

rlhis member 42 is slidably mounted upon the plate 43,secured to or formed integral with the upper end of the frame 11. said plate 43 extending into a groove in the under face of the member 42 and :forming a guide therefor. This slidable member is provided on/one side with a slot 44. which is positioned a lever pivoted to the frame 11 at 46 and having at its upper end an operating handle 47.

The walls of the slot 44 are curved and bear against the edges of the lever 45 so that when the operator actuates the handle 47, the member 42 may be adjusted lengthwise of the plate 43, and secured in an adjusted position by means of the clampinfi bolt extending through a slot in tl slidable memberH 42.

The front end of the slidable member 42 ,ces

has an opening 52 extending therethrough, in which is positie-neo the operating end of the Apresser foot or worlofeeding member 54.

The rear end of the presser foot 54 ej;- tends through a transverse slot in the upper end of a rod and is clamped in position therein byy means of a nut 56. By releasing this nut 56 from contact with the workfeeding member 54, the said presser foot 54 may be moved endwise in the slot and again clamped te the member in its adjusted position relatively thereto.

The rod 55 extends through a bearing in member 57 adapted to oscillate about a fulcrum pin 58 secured to the frame 11, and projecting through a downwardly extendflange 57X on said member 57.

"l e lower end of the rod 55 is secured in a housing 59 having a cylindrical opening therethrough, fitted to the eccentric 17.

lllhen the shaft 13 is rotated, therotation of the eccentric 17 will cause the rod 55 to be raised and lowered, and also tilted about tl a axis of the fulcrum pin 53. As a consequence of this morement, the operating end of the work-feeding member, or presser foot, y t, will be brought yinto contact with the ork and impinge thereon, and then irovethe work a. slight distance before said operating end of said presser foot 54 is again raised from contact with. said work to return to its normal position.

The front cud of the plate 43 has secured thereto a welt gage 60, by means of a screw 61. Beneath the 60 is the chisel 62.

The chisel 62 is secured. by means of a screw 63, or some other device, to a vertical rod mounted in a bearing 65 in the frame i. and haring its lower end clamped to a split member 66 by means of the screw 67.

This member 66 extends through a bea-ring 66 in a member 69, the lower end of which is provided with a cylindrical opening tl'ierethrough to receive the eccentric 16.l

the shaft 13 rotates, the revolution of the eccentric 16 will cause the chisel supporting member 64 to be reciprocated in its bearing 65. lWhen in the extreme of its upper movement. the edge of the chisel 62 is en'ibeddeu slightly in the lower ace of the welt gave 60, which is made of bronze or some similar soft u'vaterial so as not to in 4iure the cutting edge of said chisel.

T he front end of the welt 60 extends beyond the sides of the plate 43 and is rounded oft' indicated at'70 to permit the shoe to be moved horizontally at various angles while in contact therewith.

l/"Vhile the channel is being cut. the cutting edge of the chisel 62 is embedded in the welt 60 and prevents the work from being moved during the cutting operation of the channelling tool.

The forked end 36 has mounted therein a incassa block 71 supported upon the alined pins 72, thus providing a means whereby said block 7l may he tiltedto accommodate itsel to various inclinations ot the work during the channelling` operationM rlfhe tilting oi the block 71 is limited in one direction by the block coming into Contact with the upper tace of the torked portion 36, while the movement in the opposite direction is limited by means oit a downwardly extending pin 73 coming into contact with the rear tace oil said forked portion 36.

The rear end ot the block 71 has a vertical groove formed therein, in which is mounted the body portion oi the channellingknife 711:, the operating' end of which extends to ward the iront ot the block with its edge substantially parallel to the upper tace ot said block.

@ne edge ot the body portion of the chanhelling;` knife 7e bevelled and coacts with a bevelled part of an adjustable pin 757 eX- tendingtrom the rear ot the block 71 beyond the Yiront tace thereofv and having a clamping' nut 76 threaded to the projecting end thereof. ly turning the nut 7 6 the channellin knite 7 L may be clamped in any desired position. By looseningthe nut, the channelling` knife may be adjusted to give varying; degrees ot cut during` the formation of the channel. p

The upper end of the block 71 is cut away below the operating end ot the channelling kni'le 7 t so that when it is desired to use the machine tor rough rounding without formin;- a channel7 the channelling knite may be Ln'ioved down belowthe upper face'ot the block so that `no cutting operation will be performed.` This cut away portion beneath. the operating part of the channellingknite also provides a means for taking` care ol' the chips termed during` the cutting ot the `channel.

y The shankBG has a longitudinal groove 77 cut therein. into which extends the reduced end of a threaded member 78, mounted in the bearing' 34- tor vsaid shank. This con- `struction provides a means tor preventing' the rotation oit the shank 36 within its bear-` ine` i p f ln theY trame 11 .is mounted a shat't 75;" havingan operatingr handle 79 secuii'ed to one end thereof. The opposite end ot this shaft 7S has a projecting` lugl S0 radiating therefrom. This lue' 80 extends into an annular groove 81 in the rear vend oi the pin 28. on which the lever 29 is mounted.

By actuatingl the handle 79 this pin 2S and all oithe parts supportedthereon may be moved lengthwise of the anis ofsaid pin 28 into any desiredposition. This construction provides a means whereby the position of the operating` end ot the channellineknife may beadjusted longitudinally relatively to the welt gage 60 and the chisel 62.

The eccentrics 16 and 17 are so timed' that in the operation koi: the machine the presser toot 54 and chisel G2 are both at their highest point at the same time, and the cam "l is so constructed as to permit the cutting` oper-- ation by the knife 74e to take place at the same time that the chisel 62 and the presser toot 54 are in their highest positions. 111s a consequence ot this condition, the chisel 62 will be in the work when the kni'ie 741 is cutting` the work to form a channel therein.

Therefore, the chisel (5i). will hold the work `from lateral movement (iluring the channel cutting operation.

The various elements are shown in this position in the drawings with the cutting knife 74. about midway et its stroke.

The shaft 13 rotates in the direction ot the arrow a, o-n Figure 1 @t the drawings, and as the eccentrics 16 and 17 rotate therewith, the presser toot 54 and chisel 62 will immediately comence to more downwardly as these eccentrics 16 and 17 rotate from theposr tions indicated in the drawings, while the knife 7 l will iirst complete the other halt ot its cutting' stroke and then remain stationary until the point 83 of the cam 15 reaches the roller 30, and at this time the knite'i will be moved to the left ot Fig'.v 1, preparatory to a new cutting' strokewhich commences when the point y Set on the cam reaches the roller 30. i

The eccentric 16 has a. the eccentric 17, owing` to the thickness ot the work, and as a consequence, the presser toot oet will come into Contact with the work preparatory to feeding just betere the chisel 62 has lett the work, and this work will then be ted a predetermined distance before the chisel (i2 on its return stroke again enters the work.

rlhe presser foot lhhaving completed this feeding operation, will again be lifted trom the work. rthe chisel (52 will he forced through a new part ot the work and the channelling knife 7a will cut a new part ot the channel in the sole. y

It will be seen that by the construction herein shown and described, the stroke of the knife 74 is divided on opposite sides ot a center line perpendicular t0 the iace lot the sole being cut. thereby producingy a cl? n-cut channel. This obviously is a Lgreatadvantage. y

On the return stroke of the cutting' knite 711, the presser 'toot 54 in contact with the work which is gripped between said presser toot 551, and the knife 74 and in this manner the work is positively ted a ,iredeterinined distance preparatory to another cuttingT stroke of said knife 79:.

By constructing' the machine as herein `shown and describedpit is possible to cut y lore? ter throw than p i oe to normal position.

Lwhen the channel is to be cut close to the edge of the sole and consequently theedge of said sole will not extend outwardly a suiiicient distance to be acted upon by said chisel.

This makes a very simple construction of machine for rough rounding soles and cutting the channels therein, which may be used for rough rounding alone or for rough rounding and channeling. The machine is also adapted to rough round soles of new sh'oes during the process of construction, or old slices during the process of repairing.

lNhen conipleted shoes are being operated. upon; the end of the member Zl2 may be used as a while bearing against the upper. When the machine is being used as a rough rounder without cutting a channel. in the sole; the knife 74 is preferably removed and the feeding member 74X inserted in its place. The upper face of the member 7e* is preferably provided with a pluralit;7 of serrations as indicated in Fig. 7. Vith this member 74X in use the presser foot 5d will force the work into contact with the serrations 85 and feed the work a predetermined distance on the return stroke of the work Asupport 36 preparatory to another cutting operation of the chisel 62.

The fulcrum pin 28 is provided with a. flange 86 which is adapted to Contact with the end of the bearing 87 for the pin 28 in the frame ll; therebT limiting the movement of said pin 28 in one direction while move- 'ment thereof in the opposite direction is limited by the projecting lug 8Oy coming into contact with the opposite face of said bearing 87.

lhen the fulcrum pin 28 has been adjusted to any desired position it may be secured in such position by means of the clamp nut 88.

It will be noted that the cam l5 is so constructed as to provide a quick cutting stroke to the knife 74 and a very slow return .t is believed that the operation and man v advantages of the invention will be readily understood without further description.
